摘　　要：目的 通过对比两台数字减影血管造影设备在椎体成形术中的辐射剂量大小,探究国产新型DSA设备的辐射水平。方法 对择期行椎体成形术的患者按其身体质量指数(BMI)相差5%范围进行配对后,分别随机分配到实验组[联影uAngio (UIuA)]和对照组[西门子Axiom Zee Biplane (SAZB)]。对比分析两台设备手术的图像质量评价、透视时间(T)、剂量-面积乘积率(DAP率)、空气比释动能率(K剂量率)以及患者手术部位躯体左右两侧入射体表剂量(ESD)大小。结果 UIuA的透视及点片图像评价与SAZB无显著差异;UIuA的DAP剂量率(31.88;24.01~44.15μGy·mm^(2)/min)显著低于SAZB(63.73;51.62~80.26μGy·mm^(2)/min),P=0.022。K剂量率比较,UIuA(4.74;3.17~5.97 mGy/min)与SAZB(5.76;4.58~8.73 mGy/min)无显著性差异(P=0.074)。联影uAngio设备患者左、右两侧ESD显著低于西门子Axiom Zee Biplane,P值均<0.05。结论 在同等图像质量评分的前提下,国产DSA设备UIuA在辐射剂量上表现优于SAZB。UIuA对降低辐射暴露从而减少放射性损害,以及对我国介入诊疗辐射安全环境的改善有重要意义。Objective To investigate the radiation performance of new domestic DSA equipment by comparing the radi ation dose of two digital subtraction angiography devices during percutaneous vertebraplasty.Methods Patients undergoing elective percutaneous vertebraplasty were randomly assigned to the trial group[United Imaging uAngio(UluA)]and the control group[Siemens Axiom Zee Biplane(SAZB)]after being matched by a 5%range of difference in their body mass index(BMI).Comparison and analysis of image quality evaluation,Fluoroscopy Time(T),Dose-Areas Product rate(DAP rate),Air Kerma rate(K rate),and Entrance Surface Dose(ESD)magnitude on the left and right sides of the patients torso at the surgical site for the two devices.Results There was no significant difference between the fluoroscopic and spot image evaluations of the UluA and the SAZB;The DAP rate of the UluA(31.88;24.01-44.15)μGy·mm²/min was significantly lower than that of the SAZB(63.73;51.62-80.26μGy·mm²/min),P=0.022.K rate was not significantly different between the UluA(4.74;3.17-5.97 mGy/min)and the SAZB(5.76;4.58-8.73 mGy/min),P=0.074.The ESD was significantly lower in the right and left sides of patients with the UluA than with the SAZB,both the P-values<O.05.Conclusion On the premise of equal image quality evaluations,the domestic DSA device UluA outperforms the SAZB in terms of radiation dose.UluA is important for reducing radiation exposure and thus radioactive damage,as well as for improving the radiation safety environment for interventional medicine in China.
